The earliest historical pillows were used from about 7000 BC - Mesopotamian civilization (Mesopotamia is located between the Tigris and Euphrates rivers - in today's Iraq). It is believed that Egyptians have softer, softer pillows, but they are not commonly used. The use of more often makes the use of stone pillars to prop up their necks, preventing the insects from crawling into their ears, mouth and nose.
In the primitive era, people used their stones or bales to raise their heads to sleep. It was probably the original pillow when they were "deep in the hills."
When I arrived in the Warring States Period, the pillows were quite elegant. In 1957, a well-preserved lacquered wooden bed was unearthed in a Tomb of the Warring States Period in Changtaiguan, Xinyang, Henan. There was a bamboo pillow on the bed. Chinese predecessors have studied pillows. The famous historian Sima Guang of the Northern Song Dynasty used a small roundwood as a pillow. When he slept, his head slipped from the pillow and he woke up immediately. After he woke up, he continued to study. He named the pillow "police pillow." In order to keep fit, to achieve the purpose of treatment during sleep, the ancients also put drugs in the pillow to treat diseases, called "medicine pillows." Li Shizhen's "Compendium of Materia Medica" said: "Bitter skin, black bean skin, mung bean skin, cassia seed ... as a pillow, to the old eye." Folks have a variety of pillows, mostly "clear fire", "to heat" purpose. In the Ming and Qing Dynasties, the middle part of the chair is often enlarged in size and made into various styles. The cut slope is easy to bear when looking up. This part of the brain is called "pillow".
